Abstract: In order to increase the number of datastreams provided by a multimedia syst em, a cluster of clusters of multimedia A/V server subsystems is provided. Each cluster in turn is comprised of a plurality of A/V servers, a shared loop architecture pluralit y of data storage devices interconnected to the A/V servers whereby any storage device is subs tantially equally accessible by any of the servers in the cluster; and a highly availa ble control server subsystem interconnected to the A/V servers and the data storage devices for controlling the A/V servers and the data storage devices. Each of the clusters is interc onnected to a high speed switch for delivery of datastreams from the cluster to the end us er. One of the control server subsystems also serves as a master control server assigning a request for a datastream to one of the clusters.

Abstract: A shared loop multimedia datastreaming server system in provided. A plurality of A/V servers have equal access to a pool of disk arrays interconnected in a shared lo op architecture such as SSA or FC-AL. Each server delivers a corresponding datastre am from the loop through an isochronous broadband connection to appropriate A/V dev ices. The A/V servers are interconnected by a control loop such as an Ethernet link. A n archive server also accessed the shared storage loop and an archive storage system. The archive server loads titles from archive to the loop as desired and serves as a backup A /V server. A high availability control server cluster interconnects to the A/V server and t he archive server to control resource management, including distribution of titles on the l oop and loading titles from the archive server and balancing the loads on the A/V server s.
